ALL discovery 2 TD5's are "cruise" ready, it
just needs "hooking up!!!.......Read On!!!

"Cruise control is a
great extra on any car. It's perfect on long motorway journeys, and
for sticking to the speed limit if you're protective of your
license. But if your Disco doesn't come with it, it must be
expensive to fit. Or is it?"

The truth
is kits can be bought for very little money, and fitted easily. The wires
are already there, so all you need to do is fit the buttons. The
cheapest place to get the parts are from a Land Rover Dealer, or
from an independent specialist who has access to genuine parts.
There are "kits" that are sold on Ebay, but they are little
overpriced in my opinion.

The parts
you will need are the steering wheel switches PartNo YUH100320 and
the cruise master switch PartNo YUH100370 for Pre facelift Disco's
(ash grey) or For Face lift YUH000170PUY (black)

First off,
it's a good idea to disconnect the battery Negative lead.
(DON'T FORGET YOU WILL NEED YOUR RADIO CODE!!!!.)This is because you'll be removing the
airbag, and you don't want it to go off while you're trying to work
on your car. There is also some debate on whether you need to let it
to discharge, but I'd advise it's a good idea to be on the safe side
by leaving it for at least 10 minutes before starting work.

Whilst waiting for the
battery to discharge, you can replace the blank switch to the right
of the steering wheel with the cruise control master switch. This is
very easy to do, just gently pull the blank switch and insert the
master switch in it's place.

Now, turn the steering
wheel 90˚ to reveal the 2 screws behind
the wheel. Use a torx screwdriver to undo these, then carefully pull
off the front of the steering wheel and unplug the airbag.

Once the
Airbag is removed, its a good idea to store it with the deployment
side facing upwards, so "if" it was to go off by accident it does
not take off like a missile!!

Now for the hard bit.
You need to cut a hole in the steering wheel. If you bought a kit
that came with the template, attach it to the right side of the
steering wheel, draw round it and then cut the hole. If you have no
template, then the hole will be a "mirror image" of the other side
where the radio controls are.

If you've cut the hole
the correct size, you should easily be able to secure the mounting
bracket and attach the switch. This is where the problem lies if you
bought the switches from the dealer as opposed to a "kit" that used
to be available from places like Discoparts as the bracket that
holds the switch is not available as a separate part.

***I
believe that the bracket and mounting screw "should" come with the
switch, check it once you have ordered it***

If it does
not come with the bracket, then you will need to make one by copying
the radio control switch bracket on the other side. Once you have
made a bracket, mount it to the steering wheel and there should be some wires hanging
down, attach these to the switch.

Reconnect the airbag
and tighten the bolts to 9NM or 7LBS ft and replace the steering wheel cover. Reconnect the battery and take
your Disco for a spin, it should now have cruise control!

It's a very
simple mod, but definitely worth doing if you don't have cruise !!
